A freshwater tank that builds itself. Every aquarium is composed from scratch: the room it stands in, the water, the substrate, the hardscape, and a community of fish that school, forage, and hold their own depth. Rearrange it, restock it, or leave it alone and let it keep making new ones.
Captures the tank itself, not the interface. Keep this tab in front while it records — browsers throttle background tabs and the video will stutter.
A 3D freshwater aquarium simulator that runs entirely in your browser. It generates a complete planted tank, stocks it with fish that school, forage, and rest, and lets you rebuild the aquascape yourself — or leave it alone and let it compose new ones.
No. Every tank opens fully aquascaped and stocked. "Create it for me" builds a new habitat from nothing, and "Stock for me" adds a compatible community with room to swim. The ecosystem score tells you when a tank is crowded or the water is off.
One hundred. Each has its own body shape, colouring, swimming gait, schooling instinct, and preferred depth. Tetras shoal in midwater, corydoras work the substrate, gouramis hang near the surface on their pectoral fins.
Yes. Save image writes a PNG of the current view. Record captures the tank as an MP4 video or an animated GIF, in landscape, portrait, or square, so it fits wherever you are posting it. Recording captures the aquarium itself, never the interface. Firefox cannot write MP4 from the browser and will produce a WebM file instead. GIF is a 256-colour format, so gradients will band and files get large quickly — it is best kept short and small.
If you want it to. Auto-cycle composes a brand new tank at an interval you choose, from three minutes up to half an hour, or stays off entirely. It pauses while the studio is open or you are moving things around, and picks up again when you stop.
No. Nothing dies, and nothing needs feeding to survive. The ecosystem score reflects bioload, oxygen, and comfort so you can tell a crowded tank from a balanced one. This is an aquarium to watch, not a pet to keep alive.
Yes. Drag to orbit, pinch to zoom, tap a fish to inspect it. On mobile hardware the renderer lowers its own resolution and thins the stocking list to hold a steady frame rate.
Yes. "Save image" in the View tab captures the current frame as a PNG at full resolution, with the interface hidden.
No. Everything runs locally in your browser through WebGL. No account, no upload, no server. The only thing kept is your auto-cycle preference, and that lives on your own device.
That is what Watch mode is for. It hides the entire interface and slowly orbits the tank. Turn on auto-cycle, go full screen, and the aquarium will keep rebuilding itself for as long as you leave it running.
